DRAIN STORAGE-PUMP.

To all whom it may concern: I

Be it known that I, CARL F. BRANDEN- BERGER, a citizen of the United States, residing at Fort Madison, in the county of Lee and State of Iowa, have invented a new and useful Drain Storage-Pump, of which the following is a specification;

The present invention appertains generally to pumps, and relates to improvements in pumps for cisterns and wells, it being the object of the invention to provide a'novel drain storage device for pumps used in shal-- low wells or cisterns, whereby when the pump is idle, the head of water above the piston or plunger will drain downwardly into the present device, to avoid freezing, and to flow back into the barrel when the pump is started, to facilitate the starting of the pumping action of the water.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides'in the combination and arrangement -of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a vertical median section of a drain storage pump embodying the present improvement, portions being broken away and others shown in elevation.

Fig. 2 is a sectional view of modification.

The pump embodies a vertical barrel or cylinder 1 having a head or reducer 2 attached to its lower end for'the connection of the main supply pipe 3, a clack or other suitable check valve 4 being seatable on the head 2 for supporting the water or other liquid thereabove within the barrel. A vacuum chamber 5 is connected to the pipe 3 to facilitate the flow of water into and through the barrel duringthe operation of the pump. A cap or head 6 is secured to the upper end of the barrel for the connection of the lower end of the eduction' or dis charge pipe 7. A piston or plunger 8 is slidable within the valve 1 and has an upwardly opening check valve 9 provided with a restricted aperture 10 which permits the head of water to drain downwardly past said valve 9 and piston, but this aperture is not sufficiently large to interfere with the Patented May 21, 1918.

pumping of the water. extends upwardly through the pipe 7, being connected at its lower end to the piston for reciprocating it to lift the water.

The present device embodies an upright drain storage chamber 12 connected at its lower end by means of a pipe 13 with the barrel 1 adjacent to the lower end thereof,

above the check valve t. This chamber 12. lSCllSPOSBCl at one side of the barrel 1, and

the pipe 13 has an upwardly projecting loop 14, providing a trap for the water between the bend thereof, and that upwardly projecting terminal of the pipe 13, which is connected to the chamber 12. That vertical portion ofthe trap between the bend of the loop 14: and chamber 12 is provided with a check valve including a casing 15 disposed therein inclosing an upwardly opening valve member 16 having a restricted aperture 17 permitting of the restricted flow of waterabove the end of said pipe on which a disk valve 20 is seatable, said valve having a central depending conical guide member 22 to guide the valve to its seat. The valve 20 is attached to the lower portion of a float 21 of any suitable construction movable vertically within. the chamber 12. An archshaped guide 23 is disposed in an upstanding position within the chamber 12 and is provided at its lower end with outturned flanges 24 clamped between the lower end of the chamber 12 and cup 18, and the float 21 is movable loosely within said guide.

- An air vent tube or pipe 25 is connected at its lower end to the upper end of the chamber 12, and its upper end extends upwardly to a suitable point for the inflow and outflow of air, being provided with a valve 26 to control the flow of air.

When the pump is idle, the head of water can drain downwardly through the aperture 10 past the piston, then through the pipe 13 past the valve 16 by way of the aperture 17 and upwardly into the drain storage chamber 12. The water in entering the chamber 12 will raise the float 21, and the air within said chamber above the water is The pump rod 11 will start easily forced out through the tube 25. The water is thus accumulated within-the chamber-l2,

and can drain downwardly sutficiently to avoid freezing above the frost line." Wl1en" the pumpis started, the suction created by the upward movement of the piston 8 will draw the water from the chamber ;,12t;hrough the pipe 13 back into the barrel 1, the valve 16 opening to permit-10f. the. free flow 30f water; past the 1 valvedirom the storage cha n-.- ber, wherebynto v prime the ,pump so that. it

lVhen the wat.er,;is discharged from the chamber ,12, the xfloat 21 will lower with the waterlevel, thereby seating; the valveQO, and stopping the flow,
